Immunity Testing - All You Need To Know

 


What Is Immunity Testing?

The immunity test, also known as an immunoglobulin blood test or serology testing is a common diagnostic method to check for the levels of the antibodies in your system, thus offering a comprehensive overview of your body’s capabilities to fight off illnesses, diseases, and infections. In most cases, an immunoglobulins screen tests three different forms of immunoglobulins. IgG, IgM, and IgA are the three types of antibodies. If the IgG, IgM, or IgA levels are abnormally low or high, it could indicate a severe health condition.

Serologic checks are blood tests that examine the blood for antibodies. A variety of laboratory methods can be used. To detect multiple disease disorders, different types of serologic testing are used.

There is one thing that all serologic studies have in common. All of them are concerned with proteins generated by your immune system. This important body system keeps you safe by killing alien invaders that could cause illness. Regardless of the serologic research methodology the laboratory employs, the procedure for getting the test is the same. Antibodies and immunoglobulins, which are proteins that appear as part of the immune system's protection against infection or disease, are looked for in serology research. The COVID serology test is looking for an antibody known as IgG, which may mean long-term defense against an infectious disease like this one.

What Is An Immunity Test Done For?

A blood test for immunoglobulins can be used to identify a number of diseases, including:


  • Viral and/or bacterial infection
  • Immunodeficiency, a medical condition, wherein the body’s ability to fight off invaders is severely reduced
  • Specific types of cancer, primarily multiple myeloma
  • Measles
  • Syphilis
  • Fungal infections
  • HIV
  • Brucellosis

How Is An ImmunityTest Done?

To perform serologic analysis, the laboratory only needs a blood sample.

The examination will take place in your doctor's office or a pathology lab. A needle would be inserted into your vein to draw blood for comparison. When doing serologic testing on a small child, the doctor can take a piece of the skin with a lancet to avoid blood draw.

The protocol for testing is simple. The majority of patients do not experience extreme pain. Excessive bleeding and contamination are possible side effects, but the likelihood of these is minimal.

 

What Do The Test Results Mean? 

Based on the test results, your immune system’s capability is determined. 

  • The absence of the antibodies in the test result is considered to be normal, as it denotes the absence of an infection. 
  • The presence of antibodies in the system means that your immune system has been active in fighting an infection, whether in the past or currently.

Why You Shouldn't Ignore Regular Diabetes Checkups

Image
The food we eat contains carbohydrates, proteins, fat, minerals, and various sorts of vitamins. Food like cereals, wheat, rice, dairy products, fruits, and sugary food contain carbohydrates that break down in our stomach and digestive system and this broken paste is converted into glucose in our stomach. The body derives its energy from this glucose to help us do daily activities and fight various ailments.    The glucose produced in the stomach goes into the bloodstreams of the body leading to higher glucose levels. Another gland called pancreas located beneath the stomach starts releasing a hormone called insulin. Both insulin and glucose enters the bloodstream supplying energy that we get from food. So basically, insulin and glucose are both essential for a healthy human body. But what happens, sometimes your body stops producing insulin resulting in higher blood sugar levels, therefore causing diabetes. Diabetes is a serious medical condition where your body ...
